处理远程通知 [英] Handling Remote Notifications

问题描述

我正在阅读如何处理开发者苹果指南上的远程通知.我的问题有两个:这句话的解释是什么

I was reading how handling remote notification on developer apple guide. My questions are two: what is the interpretation of the phrase

当应用程序未运行时传递通知前景

The notification is delivered when the application isn’t running in the foreground

is not running in the foreground 覆盖了后台并且不运行或只是在后台状态.根据解释，以下句子:

isn’t running in the foreground covers background and not running or in the background state just. Based on the interpretation, the following sentence:

在运行 iOS 的设备上点击应用程序图标，应用程序调用相同的方法，但不提供有关通知的信息.

the application icon is tapped on a device running iOS, the application calls the same method, but furnishes no information about the notification.

有不同的意义.

第二个问题是关于我连续收到两次远程通知的情况:当我在方法中打开app时

The second question concerns the situation where I get two consecutive remote notifications: When I open the app in the method

应用程序:didFinishLaunchingWithOptions:或者应用程序:didReceiveRemoteNotification:

application:didFinishLaunchingWithOptions: or application:didReceiveRemoteNotification:

我有关于所有通知的信息还是只有最后一条?

I have information on all notifications or just the last?

推荐答案

• 如果您的应用程序正在运行，无论是在后台挂起状态还是在前台，收到通知时调用的方法将始终是 application:didReceiveRemoteNotification:.
• 如果您的应用程序根本没有运行，在收到通知后启动时，它将触发 application:didFinishLaunchingWithOptions: 并且选项将是一个 non-nil 对象包含有关您的远程通知的信息.
• 据我所知，只有最后一条通知信息可用.
• If your application is running, either in background suspended state or foreground, the method that will get called upon receiving a notification will always be application:didReceiveRemoteNotification:.
• If your application is not running at all, upon launch after receiving a notification, it will trigger application:didFinishLaunchingWithOptions: and the options will be a non-nil object containing information about your remote notification.
• As far as I know, only the last notification info is available.
